EthCreateFilter

  • Article

This function is called by a network adapter driver. It creates and initializes an Ethernet filter library database associated with one network interface card (network adapter).

BOOLEAN EthCreateFilter(
IN UINT MaximumMulticastAddresses,
IN ETH_ADDRESS_CHANGE AddressChangeAction, 
IN ETH_FILTER_CHANGE FilterChangeAction, 
IN ETH_DEFERRED_CLOSE CloseAction,
IN PUCHAR AdapterAddress,
IN PNDIS_SPIN_LOCK Lock,
OUT PETH_FILTER *Filter );

Parameters

  • MaximumMulticastAddresses
    Specifies the maximum number of multicast addresses supported by the filter.
  • AddressChangeAction
    Handle to the caller's MacChangeEthAddresses function, which the Ethernet filter library calls when a change occurs in the list of multicast addresses that the network interface card enables.
  • FilterChangeAction
    Handle to the caller's MacChangeFilter function, which the Ethernet filter library calls when a binding sets or clears a particular filter class. The binding must be the first or only binding using the filter class.
  • CloseAction
    Specifies the address of the caller's MacCloseAction function, which the Ethernet filter library calls if a binding closes while it is indicating incoming data through the NdisMEthIndicateReceive function.
  • AdapterAddress
    Pointer to the network address of the network adapter.
  • Lock
    Pointer to an initialized spin lock that the driver must hold when it requires exclusive access to the Ethernet filter library database.
  • Filter
    Pointer to a caller-supplied variable in which this function writes a pointer to the created filter.

Return Values

TRUE indicates success.

Remarks

The network adapter driver uses the Ethernet filter library to filter received network packets. Using the destination address of a received packet, the filter library determines the protocol driver bindings that receive indications for the packet.
